Summary
The United States Court of Appeals for the Federal Circuit affirmed the district court’s denial of Polygroup’s motion for judgment as a matter of law that claim 15 of Willis Electric’s patent was obvious. The court held that substantial evidence supported the jury’s finding that a skilled artisan would not have been motivated to modify the prior-art artificial tree design to use coaxial connectors. The court also affirmed the denial of a new trial on damages, concluding that the damages expert’s apportionment and methodology presented admissible evidence for the jury’s consideration.

Questions Presented
- Whether the district court erred in denying JMOL because no reasonable jury could find claim 15 nonobvious.
- Whether substantial evidence supported the jury's presumed factual finding that a skilled artisan would not have been motivated to modify the Loomis GKI Tree to use coaxial barrel connectors.
- Whether the district court abused its discretion by denying a new trial on damages and allowing Riley's reasonable-royalty testimony under Federal Rule of Evidence 702.
- Whether Riley adequately apportioned damages to the value of claim 15 and reliably used income-based, market-based, and Georgia-Pacific methodologies.
Holdings
- The district court properly denied JMOL because substantial evidence supported the jury's presumed factual finding that a skilled artisan would not have been motivated to modify the Loomis GKI Tree to use coaxial connectors; claim 15 therefore was not shown to be obvious as a matter of law.
- A patentee may rely on value attributable to claim 10's simultaneous, rotationally independent mechanical and electrical connection when assessing the incremental value of claim 15's coaxial connectors, because the IPR determination that claim 10 was unpatentable used a different claim construction and did not preclude reliance on that functionality under the district court's construction.
- The district court did not abuse its discretion in admitting Riley's damages testimony and denying a new trial because her apportionment and reasonable-royalty methodologies were sufficiently relevant and reliable under Rule 702; criticisms concerning modeling choices, data selection, license comparability, and presentation generally went to weight rather than admissibility.
- Rule 702 and Federal Circuit precedent do not require an expert to assign a numerical value to every qualitative Georgia-Pacific factor; an expert may use qualitative factors to determine where a reasonable royalty falls within an already-apportioned numerical range.
Key quotations
“Our role is not to reweigh the evidence.” (9)
“As the gatekeeper, the district court has the exclusive role of assessing the reliability of the testimony based on the full breadth of information before it.” (14)
“Where the methodology is reasonable and its data or evidence are sufficiently tied to the facts of the case, the gatekeeping role of the court is satisfied, and the inquiry on the correctness of the methodology and of the results produced thereunder belongs to the factfinder.” (27)
“Rule 702 does not require the district court to exclude expert testimony simply because the expert’s qualitative judgments in a field of “approximation and uncertainty” might, at least theoretically, have been more precisely quantified.” (37)
Factual background
Willis owns U.S. Patent No. 8,454,186, which concerns pre-lit artificial trees with modular trunk portions that make simultaneous mechanical and electrical connections regardless of rotational orientation. Polygroup's accused Quick Set trees used related internal connection technology. At trial, the jury found claim 15, which requires coaxial trunk connectors, infringed and not invalid and awarded Willis $42,494,772 based on a reasonable-royalty theory supported by damages expert Michele Riley.
Procedural history
Willis sued Polygroup for patent infringement involving pre-lit artificial trees. After inter partes review proceedings and related appeals left claim 15 of U.S. Patent No. 8,454,186 for trial, a jury found claim 15 infringed and not invalid and awarded $42,494,772 in damages. The district court denied Polygroup's motions for JMOL of obviousness and a new trial on damages, and Polygroup appealed.
